10 main reasons for Vibrations in Pumps - Anti-Vibration Mounts for Pumps

Anti-Vibration Mounts isolating pump vibrations 

Vibration exists in all pumps and indeed all rotating machines. Pumps produce vibrations in horizontal and vertical planes and also exert centrifugal and torsional vibrations. All these vibrations can be isolated by using appropriate Anti-Vibration Mounts for mounting these pumps and other rotating machinery. Pump designers (and motor designers) design machines to withstand normal vibration limits. These vibration isolation limits vary by pump type, mounting configuration, power requirements, rotation speed and the type of fluid being pumped. Even these vibration limits are sometimes very high considering the other machinery to be placed in the vicinity of these pumps and thus Anti-Vibration Mounts are required for mounting these pumps.

Excessive vibration in pumps may lead to excessive noise, equipment damage, and premature pump failure due to fatigue.


The 10 Main causes of Vibrations in Pumps and Motors are due to:

★ Misapplication, design, or manufacturing defect causing vibrations in Pumps. 

★ Corrosion and erosion - Damage from corrosion or erosion may damage impellers or rings, leading to a machine which vibrates beyond acceptable limits. 

★ Imbalance of the Impeller - Impellers should be trimmed and dynamically balanced to the proper diameter at the maximum operating speed. Initial failure to balance the impeller on an existing pump may well cause vibration outside of acceptable areas. 

★ Imbalance of motor rotating element - This is a rare manufacturing flaw. 

★ Coupling out of balance.

 

★ Incorrect rotation - While pumps will pump when rotating in the wrong direction, flow and head will be reduced and vibration due to fluid dynamics may result. 

★ Bent shaft - A bent shaft may be caused by a number of field related issues and will result in vibration. 

★ Bearing wear / failure - Lack of lubrication or improper lubrication may hasten bearing wear and cause vibration. 

★ Pipe strain (misalignment between the pump and the piping) - Pipe strain is the number one cause of vibration issues in pumps.

★ Poor foundation or anchoring - If the pump's foundation is not flat or the baseplate not properly secured or grouted, vibration will be increased. The pump may be mounted on Anti-Vibration mounts to reduce the overall vibration levels being transmitted onto the base plate.

By Choosing the correct Anti-Vibration Mounts, these vibrations can be greatly reduced and damped.

★ Our Anti-Vibration Mounts are made from Elastomeric Composite Material providing high vibration isolation for motors and pumps.
★ The Anti-Vibration Mounts for Pumps are made from Zinc Plated corrosion resitant steel metal sheets for superior working life.
★ The Anti-Vibration Mounts are very easy to install below pumps and motors as per our Anti-Vibration Mounts Installation Guidelines.
★ These Anti-Vibration Mounts are Heavy-Duty Vibration Isolation Mounts with superior metallics steel plates at top and bottom for secure mounting.
★ These pump mounts for vibration isolation are available in various sizes and can absorb vibrations in various Pumps ranging from 20Kg to 5,000Kg.
